Active clinical trials for "Sclerosis"

The primary purpose of this study is to evaluate the overall safety and efficacy of Tecfidera (Dimethyl Fumarate) as an oral treatment for Korean participants with relapsing-remitting multiple sclerosis (MS) under routine clinical practice.

This is a Phase IV, prospective, open-label, single-center, observational, longitudinal, single blinded study. The investigators will examine the effects of Ocrelizumab on cognitive, patient reported outcomes (PROs), quality of life (QoL), multiple sclerosis functional composite (MSFC), working status and magnetic resonance imaging (MRI) outcomes across 12 and 24 months.

This study will examine the impacts of two different methods of managing MS-related spasticity of the lower limbs. Both interventions will be presented via video teleconference in group classes consisting of exercises to reduce spasticity.

Validating a peptide-based laboratory test enabling the measurement of Tysabri® serum levels (pharmacokinetics, PK) in multiple sclerosis patients undergoing therapy. The results of this newly developed test will be compared to Tysabri® serum levels measured in parallel using an independent test. We will also simultaneously measure a pharmacodynamic marker of Tysabri®, receptor saturation levels on blood immune cells, which is thought to correlate with Tysabri® serum levels.

The proposed observational trial will collect substantial data concerning dietary intake documented by ALS patients complemented by the analysis of fatty acid distribution in erythrocyte lipids. Both data sets are related to disease status and progress.

Patients with multiple sclerosis (MS) may show chronic signs of optic neuropathy (CON) that may follow acute optic neuritis (secondary form of CON, S-CON) or occur independently of any acute demyelinating lesion of the optic nerve (primary form of CON, P-CON). In both S-CON and P-CON, a long term progressive ganglion cell axonal loss occurs. This axonal damage could be secondary to retrograde atrophy of axons within plaques of demyelination or a primary progressive degeneration of ganglion cells, but the underlying physiopathology has not been fully questioned in the different profile types of CON. In this project, investigators aim at understanding the pathophysiology of S-CON and P-CON, i.e. secondary to demyelination or primary degeneration, in patients complaining of persistent visual complaints. In a first cross sectional study, 30 MS patients with mild to moderate P-CPON or S-CON and 30 age-matched control subjects will perform an extensive neuro-ophthalmological assessment including clinical examination, visual evoked potentials (pattern and low contrast), electroretinogram (pattern and multifocal ERG), OCT (peripapillary and macular volume scan segmentation protocols) and MRI of the optic nerve. In these patients with mild to moderate CON, investigators aim at differentiating patients showing predominant demyelination from those showing pure or predominant axonal degeneration. Visual function assessment and degree of axonal degeneration will be compared and correlated in the two types of underlying pathophysiology and in the group of control subject. In a following longitudinal study, the patients will be re-assessed a year later in order to evaluate the progression of CON in both profile types. Our hypothesis would be that visual function and progression is worse in the degeneration group as compared to the demyelination group. This study should help to find reliable measures of the pathophysiology of CON and correlate it with the long-term visual prognostic of the disease.

The purpose of this study is to determine whether a training program in the use of ambulatory assistive devices (such as canes, walkers, etc) can reduce falls and increase functional mobility and neural connectivity in people with Multiple Sclerosis.

The purpose of the study is to develop an improved understanding of the long term pharmacokinetics and pharmacodynamics of natalizumab with both standard dosing and extended dosing, and collect additional samples to explore cell-based biomarkers of natalizumab treatment and PML risk.

To determine a correlation between serum leptin levels, nitric oxide preceding a relapse and change in leptin and nitric oxide levels during exacerbation in relapsing remitting multiple sclerosis patients.

The aim of the SEPLUS study is to evaluate the patients characteristics associated with adherence to Betaferon over a 24-month follow up period after the initiation of Betaferon in the BetaPlus program
